Functions

func Decrypt

func Decrypt(msg []byte, key *[KeySize]byte) ([]byte, error)

Decrypt extracts the nonce from the encrypted text, and attempts to decrypt with nacl.box.

func Encrypt

func Encrypt(msg []byte, key *[KeySize]byte) ([]byte, error)

Encrypt generates a random nonce and encrypts the input using nacl.secretbox package. We store the nonce in the first 24 bytes of the encrypted text.

func GenerateKey

func GenerateKey() (*[KeySize]byte, error)

GenerateKey generates a new random secret key.

func GenerateNonce

func GenerateNonce() (*[NonceSize]byte, error)

GenerateNonce creates a new random nonce.
